habitat
Montane coniferous forest.

seasonality
Adults have been collected in Alberta in July and early August.

identification
A medium-size moth (3.0-3.4 cm wingspan) with dark and light grey mottled forewings and brown hindwings. Forewings are dark grey mottled with lighter, somewhat shiny lighter grey scales. The area below the stigma is not darker than the rest of the wing, like it is in most similar species of Syngrapha. The stigma is a pale green-gold or pale gold V or U-shape, higher than wide, with a small separate satellite spot. Hindwings are light yellow brown, shading to a wide sooty brown terminal band. The antennae are simple and the sexes are alike.

life history
Adults are nocturnal and come to light. The larvae are solitary defoliators of conifers. There is a single brood each season.

conservation
A fairly common and widespread species with secure habitat.

diet info
No specific Alberta data; in western Canada, it has been reared from subalpine fir (Abies lasiocarpa) and Englemann spruce (Picea englemanni).

range
A western species, ranging from Alaska south in the mountains to northern Oregon, western Nevada, Arizona and New Mexico and east to Colorado, western Wyoming, Montana and Alberta. In Alberta, it has been collected throughout the mountains, north to the Grande Cache area.
